I'm attempting to install mySQL from source on Mac OS X. /usr/local persmissions indicate only root has write permission. The instructions have several steps shown as if the administrative account is installing into /usr/local without using sudo. I'm missing something because my administrative account will not allow me to write to /usr/local because of the permissions of root. drwxr-xr-x 3 root wheel 102 17 Jul 11:28 .
